I mean tanks focusing on DPS has ALWAYS been the case within XIV, if you're oblivious to it, then you really haven't done much in the way of meaningful content as a tank. There are other games out there where you hit enemies as if you were using a foam bat and have like 5 skills and you mash your defensive button before the damage comes in, if that's more to your liking. But, this is how XIV tanking and combat in general works, it's about getting as much damage out as possible to meet DPS checks. There is casual content where the DPS check is non existent within XIV which you can stick to, but don't gatekeep the higher end of the player base just because you don't like the DPS centric meta that has been around for forever.
